    On-line the new way of recruiting: IT-companies hiring process: a case study of Netcom Consultants and Moore BCS2002Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The purpose with this thesis is to describe the hiring process for IT- companies and to describe the different steps in the on-line hiring process compared to the steps in the traditional hiring process. In today's society where people change jobs more often, it is important for the companies to come up with a working hiring process that is both fast and reliable. To be able to study the hiring process for IT-companies, I did a case study of two similar companies, one in Sweden and one in the USA. I used a qualitative study with interviews both in person and via phone. The result I got was that IT-companies are using a mixed form of the traditional and the on-line hiring processes. They do not trust the on-line process all the way and are therefore using part of it, which give them more control. The differences between the two processes is that the on-line process tries to make the process more automatically and shorten the time it takes for every step.

    Rävelden: Dola Suite2016Other (Other academic)
    Abstract [en]

    The album Dola Suite (Rävelden) was released in May of 2016 through the Italian label Setola Di Maiale.

    Luigi Bozzolan - piano

    Torbjörn Ömalm - electric guitar

    Markus Larsson - drums/percussion

    Feat. Achille Succi - alto sax and bass clarinet

    Engineered, recorded and mixed by Johan Karlsson at Twin City Choir Studios, October 2015 in Malmberget – Sweden. Mastered by Ronald Vikström in February 2016. All songs written/improvised by Rävelden.

    The trio is based in Gällivare, Swedish Lapland, and plays music that is based on a collective improvisation following its own identity. Achille Succi contributed with some really superb musicianship to the trio in a vibrant arctic studiosession.

    A "Dola" is an explosive that has failed to detonate for some reason and we tried to improvise out of that idea in this three part suite.

    Rävelden: Live at 800 M.Ö.H in July 20162016Other (Other academic)
    Abstract [en]

    Rävelden trio performed a concert at the festival 800 M.Ö.H.arranged on Dundret, Gällivare by Shapepahs in July 2016. 

    The idea behind "To play a mountain” with Rävelden at 800 MÖH came loosely from reading articles circulating around Sámi culture written from within the Sámi culture. Torbjörn Ömalm started to reflect around the phenomenon when a Sámi jojks a place, a person, a story. In parallel different mouth sounds that mimic what happened in the situation, such as imitations of animal sounds is sometimes used in different areas of Sápmi. Ömalm started to think about the possibilities of apply this way of thinking to instrumental music in ensemble situations. To jojk instrumentally; is it possible? To play ones surrounding. 

    Playing this mountain Dundret is a lot about finding new ways of collective improvisation; in this case out of a specific cultural and geographical context point and inside a cultural context. We improvise with a common goal, a common agenda expressed individually and collectively. At the concert, Rävelden improvised 4 pieces of music during 30 minutes out of this idea basis.

    The concert is a part of Torbjörn Ömalm's artistic PhD-work and will later be presented as a paper/article (sound + written text) in relation to his thesis.

    Rävelden trio is:

    Torbjörn Ömalm - guitar

    Luigi Bozzolan -piano

    Markus Larsson - drums

    The show was filmed by Torbjörn Ömalm.

    Dundret, or Váhtjerduottar in Sámi-language (English: Váhtjirs mountain) is a lowland mountain located nearby the town of Gällivare in Swedish Lapland. The finnish/meänkieli-speaking population in the region also calls the mountain Vasaratunturi. Váhtjir was a sámi reindeer herder that possessed the area around Dundret between 1557-1604 as a “Lappskatteland”, an area that he paid taxes for (Falck & Korhonen, 2008). The area is also known for multiple olden relics consisting of holy sacrificial grounds, old fireplaces, old housing foundations and other old traces of Sámi population etc. (Riksantikvarieämbetet, 2016). For a lot of people living in the area, there is some hard-to-describe feeling of mysticism around this place.

    "A close friend of mine once said to me that Gällivare is Sweden's Twin Peaks (edit: a David Lynch creation). Not to confuse reality with television series but yes anyway more fun than that ... The town inherit a lot of “originals” as taken from a David Lynch screenplay; a large dark forest in all directions, some kind of remnant of old nature religions and superstitions remain, manalaiset and goblins. Suppressed emotions and intrigue. No sawmill but a mine." - Johan Airijoki – singer/songwriter

    Ulu – språk som byggsten i instrumentalmusik2016In: Musikforskning i dag, Växjö, 2016, p. 32-33Conference paper (Refereed)
    Abstract [sv]

    Ulu är ett delexperiment inom ett konstnärligt forskningsarbete som går under arbetsnamnet Att tonsätta en kulturmiljö – minoritetspråk och kultur som grund i musikaliskt skapande. Detta första experiment grundar sig i en transkription, musikalisk bearbetning och tolkning av en äldre fältinspelning gjord i Gällivare kommun med en meänkieli-modersmålstalande man från skogsbyn Satter. Mitt huvudinstrument är gitarr (i olika former) vilket även fungerar som mitt främsta verktyg under arbetets gång. Metoderna står i tät relation till och utvecklas utifrån tidigare konstnärligt arbete kring språk och språkljud av musiker/kompositörer som Peter Ablinger (1998), Jason Moran (2003) och Hermeto Pascoal (1992). Hur låter ett språk rent musikaliskt och genom musikalisk praktik? Syftet med experimentet är att undersöka möjligheter till att använda specifika språkmiljöer, dess melodier och rytmer som direkta byggstenar i musikaliska skapelseprocesser samt som grund i improvisationer utifrån varierande musikgenrer. Valet av Ulu ́s röst grundar sig i dess rytmiska distinkthet samtidigt som den har ett stort vibrerande och atmosfäriskt klangdjup inom sig. Ett annat skäl är att man tydligt hör biljud som ex. harklingar, andningsljud och stol/bordknackningar vilket förstärker den visuella bilden av intervjusituationen. Det transkriberade materialet används och prövas genom videodokumenterade delmoment. Delexperimentet Ulu är ett av två experiment som kommer att resultera i ett första paper under 2016 vilken kommer att vara en nyckeldel inom min doktorand. Ulu presenteras genom en muntlig föreläsning samt via uppspelning av klingande material.

    Váhtjerduottar: To play a mountain 2017Conference paper (Refereed)
    Abstract [sv]

     Språk-, natur- och kulturmiljöer, såväl inhemska som främmande, har sedan länge fascinerat och inspirerat konstnärer, musiker och kompositörer inom vitt skilda genrer under olika tidsepoker. Inom den samiska kulturen finns bruket att jojka en plats, en person eller händelse. Hur kan man använda sig av en liknande utgångspunkt vid ett kollektivt improviserande musikskapande som sker i stunden, i realtid? Hur kan man på ett konstnärligt begripligt och konkret sätt använda sig av inspiration från specifika geografiska regioner, händelser och etnologiska företeelser vid musikskapande? Hur påverkar kunskapen om och erfarenheten av en specifik kulturmiljö ens konstnärliga uttryck? Vilka nödvändiga metoder och verktyg växer fram under den sökande processen? I Váhtjerduottar beskrivs en videodokumenterad improviserad utomhusfestivalkonsert på lågfjället Dundret i Gällivare med frijazztrion Rävelden där musikerna spelar/interagerar utifrån en kollektiv agenda om att “spela en plats”, att försöka vara ett med elementen just där och då. Trion jobbar utifrån instrumentsättningen gitarr, piano och trummor/percussion med mer eller mindreo konventionella metoder. Musikernas respektive bakgrunder, deras inställning före konserten och deras analyser efteråt färgar huvudfrågan och ger flerdimensionella svar kring denna riktade kollektiva improvisation som utfördes på en kulturgeografiskt samisk plats. Denna arbetsprocess har alstrat nya metoder som kan tänkas bidra till att enklare kunna “avkoda”, hantera och realisera impulser vid musikskapande och framförande av musik som är avsedd att ljuda av specifika platser, miljöer och händelser. Läsaren och lyssnaren får en inblick i de individuella kreativa processer som omgärdar detta arbete genom en föreläsning där uppspelning av klingande material ingår.

    Differentierad lönestruktur bland lärare: -på väg mot en "tredjelärare"?2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The reforms in the Swedish school system have been many in recent decades, and there is a dissatisfaction among today's teachers who are clear. Teachers 'Union Chairman Eva-Lis Sirén pronounced in an article on the Teachers' Association's website that teacher wages are a social problem. In 2013, the government introduced state grants to the school principals who set up a career ladder for teachers and in 2016, the teacher payroll was introduced. These reforms would increase the attractiveness of the profession by praising especially skilled teachers. With the now introduced state grants, there has been a sudden and powerful pay gap among teachers, which means a whole new situation. This then about 40 percent of the teachers are considered particularly skilled and then awarded a salary increase. The purpose of the study was to investigate how teachers experience their working conditions, focusing on cooperation and individual payroll. To answer the purpose, the following questions were asked: How do the teachers describe the cooperation within their working groups? If and if so what possible and preventive factors for collaboration teachers can be identified? How do the teachers describe the individual payroll and thus the large and fast pay differential? What opportunities and barriers to cooperation can be understood in relation to the large and rapid salary differential? The method came to be qualitative as the purpose demanded a subjective reality, the empirical material consisted of six interviews conducted with professional teachers in upper secondary school context. The rest of the paper has consisted of relevant literature, scientific articles and various Internet sources. The result showed that teachers working conditions were influenced by the sudden wage differential and this in the form of neglect, dissatisfaction and verbal conflicts. Individual wages were generally considered good, but good and bad when there was a dissatisfaction that in one sentence it was unfair.

    Från arbetslöshet till arbetsliv via utbildning: En sekundäranalys om möjligheter och hinder2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The lack of educated labor causes difficulties for companies to recruit and grow at the same time as the economy in the society is affected negatively. Statistics shows that there is often a link between level of education and unemployment. The importance of the education is described by Unesco and has an impact on poverty, health and well-being, growth and citizenship. One of the goals is that everyone has the right to equivalent education that is of good quality and provide the individual with the conditions for lifelong learning. Despite this goal, labor shortages such as unemployment are social problems where necessary actions need to be taken. Being unemployed means that the individual is outside the labor market, completely or partially, for a shorter or a longer period of time. As unemployed the individual can be available to the labor market through an established contact with Arbetsförmedlingen. The actions that is taken by the Government mean that more people will educate themselves and thus will the competence of the individual increase the opportunities to approach the labor market. For the individual, the decision to educate themselves can either be seen as an opportunity or an obstacle.

    Går det att styra med mål?: En jämförande fallstudie mellan Göteborg och Stockholm2013Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Most Swedish municipalities and county councils use some form of management by objectives and results, a management model with the purpose of clarifying and organising the roles of politics and administration, particularly against the background of balanced budget requirements. After the advent of efficiency-inspired New Public Management, management by objectives and results also turned into a political reality in Sweden at the end of the 1980s and continued to expand, supported by management principles borrowed from the private sector. This has had a profound impact on the role and dynamics of political control. Against the theoretical background of management by objectives and an operationalization of how local objectives are formulated, I chose to investigate Sweden’s two largest municipalities, Stockholm and Göteborg, their regulatory documents and annual committee reports for 2012, with particular focus on a non-statutory sector (culture), in order to see whether political control actually can be determined from the local chain of command as applied via these documents over the last decades. The result is that it was not possible to say with certainty on the basis of the regulatory documents that I examined whether political control has been exerted in the sector studied.

    Crafting a Cricket Batsman Robot2006Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The creation of a cricket batsman robot is part of a larger research project within collaborative robotic behaviour. The ultimate goals are complete robot cricket teams working and playing together in a simplified form of cricket. The demands of such robotic units are not only the limitation in resource availability but also the need of being simple, robust and easy to duplicate. It is a journey into the world of microcontrollers, where mechanics, electronics and software come together forming a miniature robotic cricket player. Presented with a basic circuit for microcontroller programming, a plastic gearbox from Taima and a few hundred dollar budget the voyage starts. Mechanical construction is done in the art of scrap heap construction, using only what is available in the local workshop. Electronic components, beside considered standard, include the PIC18F452-microcontroller, GP2D02 range sensors and ZD1901 photo interrupters. They together cost less than 50 Australian dollars. Software is produced using MPLAB and Microchips own student c-compiler. Considering development cost is zero, the robot design landed greatly below budget. Two robots where produced. One to be kept at the department of electrical engineering at Monash University Clayton Australia and the other to be shown at my home university in Luleå.

    Närståendes upplevelser av att leva tillsammans med en person med Parkinsons sjukdom: En litteraturstudie2017Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Parkinsons sjukdom är en progressiv kronisk sjukdom som ger en tilltagande försämring av motoriska och kognitiva funktioner. Många personer med Parkinsons sjukdom bor kvar i hemmet och får ett ökat behov av stöd och hjälp. De som tillgodoser detta behov av omvårdnad är ofta närstående som vårdar personen. Detta kan få en påverkan på närståendes hälsa ochlivskvalité. Syftet med denna studie var att beskriva närståendes upplevelser av att leva tillsammans med en person med Parkinsons sjukdom. Tolv vetenskapliga artiklar valdes ut via en litteratursökning och analyserades genom en kvalitativ innehållsanalys med manifest ansats enligt Bengtsson(2016). Analysen resulterade i sex olika slutkategorier; att ha behov av information och kunskap om sjukdomen, att ha behov av stöd och fungerande sjukvård, att livet och vardagen förändras vilket kan skapa ensamhet och isolering, att relationer förändras och ger nya förhållningssätt, att vilja orka vårda och känna oro för att inte räcka till, att känna osäkerhet och behöva ta svåra beslut. Resultatet visade att närstående saknade information, hade ett stort behov av stöd, livet och vardagen förändrades samt skapade ensamhet och isolering och relationer förändrades. Slutsatsen är att sjuksköterskor måste synliggöra närstående som en viktig del i omvårdnaden samt att ge närstående bra förutsättningar att klara det dagliga livet.

    Angry Voices from the Past and Present: Effects on Adults' and Children's Earwitness Memory2013In: Journal of Investigative Psychology and Offender Profiling, ISSN 1544-4759, E-ISSN 1544-4767, Vol. 10, no 1, p. 57-70Article in journal (Refereed)
    Abstract [en]

    The major aim was to examine the effect of the perpetrator’s tone of voice and time delay on voice recognition. In addition, the effect of two types of voice description interviews intended to strengthen voice encoding was tested. Both 11- to 13-year-olds (n = 160) and adults (n = 148) heard an unfamiliar voice for 40 s. The perpetrator either spoke in a normal tone at encoding and in the lineup (congruent), or in an angry tone at encoding and a normal tone in the lineup (incongruent). Witnesses were then interviewed about the voice with global questions or by rating voice characteristics. Half of the witnesses were presented with a lineup shortly after the interview (immediate) and the others after 2 weeks (delayed). Children tested immediately made significantly more correct identifications. This was not the case for adults. (In)congruency between tone of voice and interview type did not significantly affect voice recognition. Witnesses in the congruent–immediate condition performed the best. However, only 25% of the children and 19% of the adults made correct identifications. Poor identification accuracy and the fact that the majority of witnesses believed they would recognise the voice later are reasons for treating voice identification evidence with great caution.

    Enhancing Adults' and Children’s Earwitness Memory: Examining Three Types of Interviews2013In: Psychiatry, Psychology and Law, ISSN 1321-8719, E-ISSN 1934-1687, Vol. 20, no 2, p. 216-229Article in journal (Refereed)
    Abstract [en]

    The aim of the study was to find ways to enhance earwitnesses’ memory for voices and content. Another aim was to evaluate an interview protocol used by the Swedish Security Service. Three different types of interviews were compared; the Cognitive Interview, the Swedish Security Service checklist, and a baseline interview. Both 11–13-year-olds (n = 119) and adults (n = 93) were exposed to an unfamiliar voice for 40 seconds and thereafter interviewed. Two weeks later, they were confronted with a seven voice line-up. The overall accuracy for correct identifications was 19.8%. No significant difference was found between the interview conditions. As for content, the results suggest that for adults, the Cognitive Interview may be beneficial for recall of a brief conversation. The checklist used by the Swedish Security Service did not have a positive effect on voice recognition, content recall or for descriptions of voices.

    Mobile phone quality vs. direct quality: How the presentation format affects earwitness identification accuracy2010In: The European Journal of Psychology Applied to Legal Context, ISSN 1889-1861, E-ISSN 1989-4007, Vol. 2, no 2, p. 161-182Article in journal (Refereed)
    Abstract [en]

    The present study aimed to gain insight into the effect of mobile phone quality on voice identification using an ecologically realistic design. A total of 165 participants were exposed to an unfamiliar voice, either directly recorded or mobile phone recorded, for 40 seconds. After a two week delay, they were asked to identify the target-voice in a 7 voice target-present line-up. We used a between- subjects design, where half of the subjects were exposed to a directly recorded line-up, and the other half to a mobile phone recorded line-up. Data analysis did not show any significant effect of presentation format or line-up format. These results suggest that the detrimental effect on voice recognition suggested by the poorer sound quality of mobile phone recordings is minimal. They also indicate that there is no benefit from conducting a mobile phone recorded line-up, if the voice is originally heard over a mobile phone. More research is needed, however, before definitive conclusions may be drawn. The overall accuracy for correct identifications was 12.7% which is expected by chance. Further, one particular foil attracted 54% of all false identifications. Future research should focus on explaining why earwitnesses perform so poorly and develop methods to improve identification accuracy.

    Overhearing the Planning of A Crime: Do Adults Outperform Children As Earwitnesses?2011In: Journal of Police and Criminal Psychology, ISSN 0882-0783, E-ISSN 1936-6469, Vol. 26, no 2, p. 118-127Article in journal (Refereed)
    Abstract [en]

    This study examined the reliability of earwitnesses using an ecologically realistic experimental set-up. A total of 282 participants, distributed over three age-groups (7–9 vs. 11–13 year olds vs. adults), were exposed to an unfamiliar voice for 40 seconds. After a two week delay, they were presented with a 7-voice lineup. Half of the participants were exposed to a target-present lineup (TP), and the other half to a target-absent lineup (TA). For both types of lineups the participants performed poorly. In the TP-condition only the 11–13-year olds (with 27% correct identifications) performed above chance level. Furthermore, in the TA-condition all age- groups showed a high willingness to make an identification (overall mean = 53%). For both groups of children, voice identification co-varied significantly with speaking rate and pitch level, as did pitch variation for the youngest children. Neither factor correlated significantly with the adults’ identifications.

    Abstract [en]

    This study uses an econometric approach to investigate the residential electricity consumption in the Nordic countries, both from a macroeconomic and a microeconomic perspective. The macroeconomic approach uses time series data (1980-2011) to investigate the relationship between residential electricity consumption and economic growth. The results show an inverted u-shaped curve for all the countries. The microeconomic approach uses panel data to identify which variables that have the biggest impact on residential electricity consumption. The results show that, number of household members and electrical space heating carry the most significance across the variables. The study concludes that the Nordic countries are on a path to lower electricity consumption implying lower costs and less environmental impact. It is plausible to think that the same results may hold in the rest of the world as they grow wealthier. We suggest a shift from electricity space heating towards other heating systems or improved insulation.

    Industrial buying behavior: a case study of industrial customers of compression moulded goods2002Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The rapid change and restructure, such as global competitiveness and alliances, in today's business environment clearly have influence on the industrial buying behavior. Although the structure and definition of industrial buying behavior remains constant, the content of buying is changing. The necessity for an industrial marketer to withstand the environments many surprises are to understand the environment in which he operates. This thesis deals with industrial buying behavior of compression moulded goods, and the aim is to provide a better understanding of the buying process, the dimensions and roles in the buying center for different buyclasses, and to point out the most important supplier selection criteria when buying compression moulded goods. In order to achieve the purpose of this research, a case study of the industrial customers Atlas Copco Tools AB and Ericsson AB was performed. The main source of empirical data was personal interviews at each company. The findings of this study indicate that the buying process may change depending on the purchase strategy. If the purchase strategy is outsourcing, some of the steps in the buying process is performed outside the buying organization. The buyclass, i.e. the "newness" of the purchase, also influence the buying process. If the purchase is of a completely new nature, the need for information is high and therefore the buying process is longer and more complex than it would have been in a straight rebuy. In a new purchase, the number of departments and individuals involved is higher. If the purchase focuses on design, the designing department is a strong influencer, and if the purchase is of standard character, most of the influence is executed by the purchasing department. If outsourcing is used, many of the deciders and influencers may be placed outside the buying organization. The study also shows that the criteria when selecting suppliers are depending on the sort of purchase. The more flexible buying process, the more important are criteria such as understanding and compliance, and if the process is strict and well structured, focus is set to prize, delivery and performance history. If the value of the purchase is high for the whole buying organization, the prize of the product purchased is less important.

    The portrayal of Christ in "The Chronicles of Narnia" by C.S. Lewis: similarities and differences in comparison with the Bible2000Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    This essay argues that the Lion Aslan in "The Chronicles of Narnia" by C.S. Lewis is a type of the biblical Christ. The first two chapters display Aslan as a type of 'Christ - The Creator' and 'Christ - The Redeemer'. The two last chapters show the similarities between Aslan and Christ, portrayed as: Son of God: Lord: King of kings: Captain of the Host: Lion of Judah: Justificator: Caller: Rewarder: Judge: Life Giver: Provider: Sanctificator: Victory Banner: Healer: Shepherd: Peace: and Omni-Present.

    Aktivitetens betydelse för hur kön görs i skolämnet idrott och hälsa2010In: Svensk Idrottsforskning: Organ för Centrum för Idrottsforskning, ISSN 1103-4629, Vol. 19, no 1, p. 52-57Article in journal (Refereed)
    Abstract [sv]

    Sluta hora med bollen, du är väl ingen tjej heller?! Platsen har visat sig ha en särskild betydelse för hur kön görs i skolan utifrån hur benämningar som hora och kärring används. Idrotten, med dess olika aktiviteter som erbjuds där, tycks vara den plats i skolmiljön där benämningarna används mest frekvent. Men man kan ställa sig frågan,har verkligen benämningar som hora och kärring betydelse när flickor och pojkar gör kön?

    Girls and boys interaction in school: how and when is sexualised language used?2005In: A Nordic dimension in education and research - myth or reality?: NFPF/NERA 33rd congress, 2005, p. 216-Conference paper (Other academic)
    Abstract [en]

    The purpose of this paper is to discuss the topic in my thesis: girls` and boys` interaction in school, focussing on their language use. An important starting point for the thesis is a pilot study, an interview with girls at an intermediate level. It shows that the girls interpret the boys to be setting up the agenda for their behaviour. My recent ethnographic study, however reveals a different scenario. A participant observation study in three different classes over a period of six weeks, shows that both girls and boys use a sexualised language. Boys use it in public addressing both girls and boys, mostly in situations where performance and competition are central. Girls use it mostly when addressing others girls in private rooms. These observations even show that when girls are together, they set up an agenda for themselves for their behaviour as well as for what kind of clothes and make-up to wear.

    Skolvardagens genusdramaturgi: en studie av hur femininiteter och maskuliniteter görs i år 5 med ett särskilt fokus på benämningar som hora och kärring2009Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The aim of the present study is to describe and analyse how pupils in 5th grade are doing femininities and masculinities in everyday school life. A particular focus is placed on how terms such as hora [‘whore'] and kärring [‘hag'] are used but also to some extent on how girls construct femininities in relation to one another through other linguistic and bodily actions. One theoretical point of departure of the study is the social constructionist perspective, in which gender is seen as something humans are doing and that individuals are active agents in this process. Raewyn Connell's theoretical framework is used. Connell argues that schools are both an institutional agent contributing to creating gender and an arena where young people stage, reinforce or renegotiate femininity and masculinity. One important point of departure of the theory is that there exist multiple femininities and masculinities that are constructed both within and between the genders in a hierarchical order. At the local level this can be studied through different kind of gender relations, which creates prevailing gender regimes. Connell thinks that these gender regimes most often vary and have different forms at the local level for example in different schools, but that they both tally with and deviate from society's overarching gender order. The empirical material of the thesis is based on an ethnographic method where field notes and participant observation were used as data collection method in three classes in the fifth form in three different schools in a medium-sized Swedish municipality. The pupils were 11-12 years old. The three schools are located in different housing areas in the centre of the municipality. One school is in a housing area that is inhabited by working-class families to a great extent and the other two schools are situated in middle-class areas.The principal result of the study shows that gender, femininities and masculinities are doing continuously in everyday school life. The place, the peer group and the activity are of great importance for how terms as "whore" and "hag" are used. In this process power and hierarchy are central components both between and within the genders. Unlike Connell, who thinks that gender regimes most often vary locally, this study shows similarities rather than differences among the three schools.

    Teaching in preschool: heads of preschools governance throughout the systematic quality work2018In: Nordic Journal of Studies in Educational Policy, ISSN 2002-0317, Vol. 4, no 1, p. 38-47Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to investigate how the heads of preschool govern teaching in practice through systematic quality work. In the new Swedish Education Act, which came into force on 1 July 2011, the mission of preschools changed because teaching was introduced as a new concept, and preschool teachers were now responsible for teaching. Swedish National Agency for Inspection report that there is a lack of how the concept of teaching is used in preschools. Heads of preschool are crucial for implementing teaching, and a valuable tool for their governing is the systematic quality work which they also are responsible for. This study collected data comprising 120 systematic quality reports from preschools in Sweden, and by text analysis, we explored how the heads of preschool used the concept of teaching. The results showed an absence of governance and management among the heads of preschool concerning teaching and when teaching is used, it was mainly according to the development of all staff competencies and to the concept of variation in teaching. This indicates that the heads of preschool govern the practice in a way that made preschool teachers responsible for teaching invisible.

    Don’t Ask Me Why: Preschool Teachers’ Knowledge in Technology as a Determinant of Leadership Behavior2018In: Journal of Technology Education, ISSN 1045-1064, Vol. 29, no 2, p. 4-19Article in journal (Refereed)
    Abstract [en]

    In the Swedish preschool curriculum, technology education is emphasized as one of the most significant pedagogical areas. Particularly, the teacher’s role is emphasized: It is the preschool teacher’s responsibility to stimulate and challenge children’s interest in science and technology. Unfortunately, prior research indicates that preschool teachers feel uncertain about what technology is and the extent of their knowledge on the topic. Based on the path–goal theory, this article will explore how preschool teachers’ knowledge of technology influence how they act toward children in different learning activities. Using a qualitative research design, this study collected data comprising 15 interviews with preschool teachers. The result provide insights for how teachers limited knowledge in technology influence their leadership behavior toward children both in planned activities initiated by teachers and in unplanned activities initiated by children during free play. The core of how teachers’ knowledge in technology influences their leadership behavior in these two types of activities is their ability to deal with children’s why questions. The results also show that a compensatory approach becomes evident in teachers’ leadership behavior toward children in planned activities and that an avoidance approach is evident in unplanned activities. Our findings suggest that the development of a problem-solving approach in unplanned activities could enable teachers to create learning environments for children in which technology becomes something natural. Moreover, enhanced knowledge and understanding of technology will in turn make teachers better able to explain and clarify concepts and various technical phenomena.

    Teachers’ leadership: A maker or breaker of students’ educational motivation2016In: School Leadership and Management, ISSN 1363-2434, E-ISSN 1364-2626, Vol. 36, no 4, p. 365-380Article in journal (Refereed)
    Abstract [en]

    Teachers’ leadership plays a critical and central role in students’ educational motivations. This indicates that, in the school context, a teacher’s leadership can have both positive and negative impacts on students’ educational motivation and performance. This article explores these assumptions, building on the path-goal theory, more specifically the effects of teachers’ leadership from students’ perspectives. Using a qualitative research design, this study collected data comprising 35 interviews with children and young people in both primary and upper-secondary school. The results show that the degree of teachers’ developmental leadership greatly affects students’ educational motivation and school performance. Two contrasting teachers’ profiles were found: teachers with a high degree of developmental leadership and teachers with a low degree of developmental leadership. Our findings suggest that teachers with the profile of a high degree of developmental leadership create an environment that fosters educational motivation positively among students, facilitating students’ achievement of high performance levels and a sense of well-being about their studies. In contrast, we show that teachers with a low degree of developmental leadership create an environment that is nonconductive for educational motivation, performance or the welfare of schoolwork.

    What motivates students?: A study on effects of teacher leadership and students' self-efficacy2018In: International Journal of Leadership in Education, ISSN 1360-3124, E-ISSN 1464-5092, Vol. 21, no 2, p. 155-175Article in journal (Refereed)
    Abstract [en]

    Students’ educational motivation is significant for performance and achieving learning, but little is known about what fuels such motivation. Educational motivation is regarded as the drive and inner state that energise educational activities, facilitate learning and channel behaviour towards achieving educational goals. Educational motivation paves the way for students to learn and acquire the knowledge that is essential for successful study outcomes. This article aims to explore what determines students’ educational motivation. Building on the self-determination theory, we modelled the influence of teachers’ leadership and students’ self-efficacy on students’ educational motivation. We used survey data from a sample of upper secondary school students in Sweden; we received a total of 993 answers, equal to a response rate of 74%. The results show that students’ self-efficacy and teacher leadership are of extreme importance for students’ educational motivation, and that highly efficacious students lose most educational motivation when the teacher’s leadership is poor. The results thus support the importance of teachers’ leadership for encouraging student learning.

    Abstract [en]

    The purpose of the study was to get increased knowledge about the work with multilingualism in small towns. With small towns is meant where the population is less than 10,000. To get this increased knowledge, five qualitative research interviews with working pre-school teachers were carried out. The study is based on Vygotskij’s sociocultural perspective; we learn from and with each other. The analysis of the interviews led to two major factors that contribute to a successful work with multilingualism in pre-school. One of them was named Knowledge, and the other one Consciousness and Engagement. The conclusions which the study gave are that First Language as a subject needs to get more space in the pre-school. Knowledge about the first language is important for the individual’s identity development and cultural belonging, but also for knowledge development in different subjects. Development in Swedish, but also in one’s second language is essential for the individual’s integration, social development in our society, and in a later stage, also for knowledge development in different subjects. An important prerequisite for a successful pre-school activity is that the children can develop their thinking and learning in their first language, simultaneously as they get the opportunity to develop the second language. A parallel language stimulation enables an effective language acquisition in both the first language and the second language, which also increases the knowledge development in other areas.

    Numerical simulations of mild wear using updated geometry with different step size approaches2001In: Wear, ISSN 0043-1648, E-ISSN 1873-2577, Vol. 249, no 1, p. 6-11Article in journal (Refereed)
    Abstract [en]

    Wear of engineering components is often a critical factor influencing the product life. Prediction and simulation of wear is therefore an important matter in engineering. Numerical simulations of wear of a cylindrical steel roller oscillating against a steel plate are performed with a special version of the finite element program NIKE2D. The simulation was done in steps and the pressure and the sliding distance was recalculated as the surface geometry changed. The wear model used in the simulations is global. The global wear model gives an opportunity to predict the change in shape of the surfaces in a fast and efficient manner, it will however not incorporate information on how the wear occurs on molecular scale.Two different strategies in selecting the time step for the geometry update were used. In the first case a larger time step was used in the first wear steps and a smaller one in the final ones, and in the second a constant time step was used. To get information on the coefficient of friction an experiment was performed. This experiment was used to evaluate the simulation as well as give the proper input to the simulation. The simulated topography of the surfaces was compared with experimental results and the agreement was good. It can be concluded that allowing the time step to differ between the wear steps will speed up the wear simulation considerably. A large time step for the geometry update will cause some waviness of the cylindrical surface but when the smaller time steps have been used at the end of the computation this error will disappear.

    Numerical simulations of wear2000Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    The objective of this licentiate thesis was to study the effect of tool wear for sheet metal forming tools and how the wear process can be simulated in an efficient manner. Three Papers are appended to this licentiate thesis. Paper A covers the influence of tool geometry in deep drawing. In paper B is the way of calculating with finite element analysis described. The wear of a steel cylinder oscillating against a steel plate was studied experimentally. The worn shape of the cylinder was then compared with a numerical simulation of the shape. Paper C shows how numerical simulations can be used to simulate wear of deep drawing tools. The wear of two different deep drawing tools has been investigated. The shape of the tools before and after wear have been compared as well as the stresses and strains in the formed cups.

    Measurement and perception of sound insulation from 20 Hz between dwellings2017Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Population growth and urbanization are projected by the United Nations to add 2,5 billionpeople to the world’s urban population by 2050. We need to construct buildings in anunprecedented scale to meet global housing demand. Sustainable development is critical.Compared to traditional heavy constructions, lightweight wooden constructions are moreenvironmentally friendly and will play a key role in meeting future demands. However, thereare two major problems with lightweight constructions that need to be addressed: 1) Limitedlow frequency sound insulation and 2) Variations in sound insulation.Annoyance from walking sound tend to be higher in lightweight than in heavy constructionseven with the same measured sound insulation. The Swedish research program AkuLiteindicated that the correlation between measured sound insulation and annoyance wassignificantly improved by extending current evaluation methods from 50 Hz down to 20 Hz.Secondly, large variations in sound insulation between nominally identical lightweightconstructions are common, which leads to larger safety margins. By identifying and quantifyingunderlying causes, production costs can be minimized and the performance can be improved.The aim of the thesis is to develop a new evaluation method for impact sound insulation thatbetter correspond to rated annoyance, and to identify and control underlying causes forvariations in sound insulation. The thesis contains six papers.In Paper I and II, sound insulation measurements were carried out in a large number ofnominally identical rooms of two different industrially prefabricated lightweight woodenconstructions. The purpose was to assess and quantify the variations in impact and airbornesound insulation. In Paper I, 30 nominally identical apartments of a volume based system wasevaluated. The apartments on the highest floor achieved significantly better sound insulationdue to the extra weight on lower floors affecting the elastic connections between stories. InPaper II, 18 rooms of a cross-laminated timber system of plate elements were evaluated.Additionally, several potential parameters related to measurement uncertainty wereinvestigated.Paper III deals with measurement uncertainty. An empirical study of reverberation timemeasurements showed that current methods need to be improved, if sound insulationrequirements are to be extended to 20 Hz.Paper IV and V verified that the frequency range 20-50 Hz is important for walking soundannoyance, and that alternative frequency adaptation terms can improve the correlation betweenmeasured impact sound insulation and annoyance ratings. In Paper IV, the methodology was toperform extensive field measurements in apartment buildings of various construction types andto perform questionnaire surveys among the residents. In Paper V, the methodology was toevaluate annoyance based on binaural recordings of walking sound in a two-part listening test.In Paper VI, 70 measurements in a lightweight wooden system were evaluated to quantify thetotal variations in impact and airborne sound insulation from 20 and 50 Hz, respectively. It wasconcluded that the proposed metrics of impact sound insulation were primarily determined bythe impact sound level 20-40 Hz and that the measurement methods must be evaluatedthoroughly to avoid excessive safety margins.

    A new evaluation method for impact sound insulation from 25 Hz, that correspond to the ratedannoyance for both heavy and lightweight constructions is proposed. By using the proposedmethod and attending the specific causes for variations, the lightweight industry will be able todevelop improved multi-story dwellings with higher perceived acoustic quality.

    Variations in sound insulation in lightweight timber constructions2010Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    This licentiate thesis deals with the topic of variations and uncertainties in building acoustic parameters for lightweight timber constructions. A higher safety margin to the legal requirements is needed to compensate for acoustical uncertainties, which leads to higher costs. Building costs can be reduced if the variations can be identified and controlled. The project was limited to industrially prefabricated timber frame based volumes and massive timber based plate elements. This thesis is based on the work reported in three papers (A, B and C). In paper A, the variations in impact and airborne sound insulation were assessed and quantified in 30 nominally identical volume built apartments in a four-storey building. Large variations were found and the underlying causes were investigated. A statistically significant difference between floor numbers was found as the highest floor achieved better sound insulation. This difference was assumed to be caused by the higher static load on lower floors affecting the elastic layer used to structurally connect the apartments. In paper B, three room volumes were followed and measured at different stages of completion throughout the construction process. The objective was to test if acoustical deviations in the field can be identified at earlier construction stages. An ISO tapping machine was used to excite the floors and the response was measured at 20 positions. The airborne and impact sound insulation were measured in the finished building. Deviations were found, but these could not be traced to earlier stages of completion. In Paper C, the variations in sound insulation of a cross-laminated timber (CLT) building system was investigated. The construction was based on prefabricated wall and floor plate elements which were mounted at the building site. A number of acoustical uncertainties related to the measurement procedure were also investigated. The measurement uncertainty was small in comparison to the total variations. The degree of prefabrication for the CLT system was lower compared to the volume system, which indicated a greater scope for poor workmanship. All papers indicate a higher sound insulation on the upper floors in a building. It is therefore important to carefully design the elastic layer between floor numbers. The measurement uncertainty has been continuously considered in this thesis. In order to properly identify and quantify variations, the measurement uncertainty should be minimised. Advantages and drawbacks with different measurement methods and directions for future research are discussed in the concluding chapters.
